Local RAG API (Open Source Edition)

A strictly local, privacy-first RAG (Retrieval Augmented Generation) backend. It allows you to ingest PDF/TXT documents and chat with them using Ollama and ChromaDB.

Status: core-logic

Features

• FastAPI: Async endpoints for /ingest and /chat.
• ChromaDB: Local vector storage.
• Ollama: Uses local LLMs (Llama 3, Mistral, etc).
• Privacy: No data leaves your machine.

Prerequisites (Manual Setup)

Since this is the source version, you must manage the infrastructure yourself:

1. Install Ollama: Download here and run ollama serve.
2. Install ChromaDB: You must run a local Chroma instance or install the python client.
3. Python 3.10+: Ensure your venv is active.

Quick Start (Source)

# 1. Install Dependencies
pip install -r requirements.txt

# 2. Pull the Embedding Model (Manual)
ollama pull llama3
ollama pull nomic-embed-text

# 3. Run the API
uvicorn src.main:app --reload
